有人可以在 Google 表格中看到这个 XIRR() 计算有什么问题吗？ （我已经向 Google 发送了一个请求……）

Question

Please review https://docs.google.com/spreadsheets/d/1cWIAdWylD5Mx8zP5gFwkSVkAYLwXuFopoH_9mi2tGWg/edit#gid=0 . It contains some dates and corresponding investment amounts. My goal is to have XIRR() compute the rate of return. While it is obvious that the result must be negative, the cell C1, with the formula XIRR(B3:B16,A3:A16) , produces a huge positive number. Thanks in advance.

Answer 1

I just realized that I didn't provide a 3rd argument, rate_guess, in the original invocation of XIRR(). (Thanks to @player0 for prompting me). With rate_guess provided, the result is believable.
